Another import format would surely be a good thing.
Anyone interested in this feature may want to take a look at pycam/Importers/STLImporter.py
. Basically you only need to create a function that receives a file-like handle and returns a mesh model (made of triangles). Afterwards you can add this new importer function to the list of handled import formats in pycam/Importers/__init__.py
. Now it should be available everywhere in pycam.
Pull requests are welcome!
Investigating pythonocc-core to see if I can do something... I can't promise anything :D
well did a bit of research and found that I'm not able to accomplish this task :D
What a pity!
Out of curiosity: is the step format too complicated or incompatible with a triangle-mesh-based data structure? Or do you think that you currently lack the python skills? (I am not trying to persuade you - I just want to prepare a good starting point for people coming back to this topic later on)
Hi
its not triangle oriented example: a curve is not composed of a lot of vertices is just a curve
I'm lacking python and opencascade skills
what I have looked at is: https://github.com/tpaviot/oce https://github.com/tpaviot/pythonocc-core
will spend some time on this :D
Edit: what most problemd gived to me was the pythonocc installation (didn't manage how to) with conda that seems the only way ... not sure sorry
here is an example of a step model: http://www.pythonocc.org/quick-examples/step-ap203-import/
Maybe pythonocc can export a model to STL? This would be the most straight-forward approach for importing step files into pycam.
stl still a mesh based format not a cad model I can export in stl from freecad
stl still a mesh based format not a cad model
Yes, indeed. Pycam uses triangle meshs internally for 3D models. Thus this no problem. I assumed that you were contemplating toolpath generation based on 3D models loaded from step files, right? Or did have something else in mind?
I can export in stl from freecad
If freecad supports a non-interactive conversion from step to stl, then this could be a simple option, too. You could take a look at pycam's PSImporter
- it uses inkscape for converting (e)ps files to DXF (which can be parsed by pycam).
Moving between the two CAD modeling schemes IGES and STEP is a non-trivial issue and has been discussed extensively in CAD forums and there are several (at least partly) successful translation options, most using CAD software that reads/writes both types of model.
I've found that FreeCAD does the trick... most of the time.
Hello
it would be very cool to have support to open step models
this can be done with OCE its only an idea
Thanks
